SFP class areas
Table 9 lists Product Name areas in the SFP class and describes each area.
NOTE
SFPs connected to GbE ports are not monitored.
Elements
Product Name defines an element as any fabric or switch component that the software monitors.
Within each area, the number of elements is equivalent to the number of components being
monitored. For instance, on a 64-port switch, each area of the Port class includes 64 elements.
Each element contains information pertaining to the description suggested by the area. To
continue the Ports example, each element in the Invalid word area of Ports would contain exactly
64 ports, each of which would contain the number of times invalid words had been received by the
port over the last time interval. Each of these elements maps to an index number, so that all
elements can be identified in terms of class, area, and index number. As an example, the
monitoring of the temperature sensor with an index of 1 can be viewed by accessing the first
temperature sensor within the temperature area of the environment class.
Subclasses are a minor exception to the preceding mapping rule. Subclasses, such as E_Ports,
contain areas with elements equivalent to the number of valid entries. Within the same example
used thus far in this section, in a 64-port switch in which eight ports are connected to another
switch, each area within the E_Port class would contain eight elements.
Each area of a subclass with defined thresholds will act in addition to the settings applied to the
element through the parent class. Assignment of elements to subclasses does not need to be
performed by a network administrator. These assignments are seamlessly made through
automated detection algorithms.
TABLE 9 SFP class areas
Area Description
Temperature Measures the physical temperature of the SFP, in degrees Celsius. A high temperature
indicates that the SFP might be in danger of damage.
Receive Power Measures the amount of incoming laser, in µwatts, to help determine if the SFP is in good
working condition. If the counter often exceeds the threshold, the SFP is deteriorating.
Transmit Power Measures the amount of outgoing laser, in µwatts. Use this to determine the condition of the
SFP. If the counter often exceeds the threshold, the SFP is deteriorating.
Current Measures the amount of supplied current to the SFP transceiver. Current area events
indicate hardware failures.
Supply Voltage Measures the amount of voltage supplied to the SFP. If this value exceeds the threshold, the
SFP is deteriorating.
